To all whom# may concern.'

Be it known that I, THOMAS. NATHAN RussELL, a citizen ofthe United Statesresiding in Chicago, in the county of Cook and State of Illinois, have invention a new and useful Improvement in Car-Roofs, of which the cap clips, the eaves ends of the seam caps lso ' Figure 1 is a vertical being closed by improved means integral with or vcarried by the c ap, so that water and dirt are excluded and the roof sheets are held j from movement away from the ridge and toward the eaves; and the seam caps are held from such movement, and therebyv enabled to so hold the roof sheets, by a connection with each other, and preferably also with'the 'ridge pole` at the ridge of .the car.

With such objects in view, as well as other advantages which may be incident to theuse of the improvements,- the invention consists in the \parts' and combinations thereof hereinafter set forth and claimed, with the understanding 'thatthe several necessary elements constituting the same may be varied in proportions and arrangement without departing from the nature and scope of the invention. w

,In order to make the invention more clearly understood there are shown in the accompanying drawings means for carrying the same into practical effect, without limiting the improvements, lin their useful applications, Vto the particular constructions which, for the purpose of explanation, haveu been made the subject of illustration. In the said drawings I v transverse section of aportion of theroof at the eaves, on the line 1-1 of Fig. 3.

tudinally of the car on the line 3--3 of Fig.- y

Fig. 4 is an `elevation of the Aouter' or 'i eaves endA of the seam cap.

Fig. 5 is a horizontal section of a portion of the latter on line 5-5 of Fig. 4.

Fi'g. 6 is a plan view, partly broken away, of a flat sheet of metal from which the seam cap isrto be formed, and showing 'the formation of the eaves end for the production of the closure of that end and the construction of the ridge end for the connection of the capat the ridge of the car.

eferring to the drawmgs, 1 indicates one -of the side plates of the roof frame, 2 the side sheathing, 3 the top sheathing, 4 the side fascia, 5 the roof sheet, (ithe seam cap, 7 the longltudinal eaves' hook strip and 8 the The hook vstrip 7 extends in' one or more. Isectlons along the eaves of the car from end to end of the latter and is formed with a depending flange 9 which is secured between the sheathings 2 and 3 and the fascia 4. With this hook strip there is loosely engaged the hooked eaves edge 10 of the roof sheet 5, as best seen in Fig. 1. The flashing 8 extends longitudinally of the car in one or l more sections, as may be lconvenient,.and is formed w1th an inwardly and upwardly ex tending flange which extends to the inner portion'of theloose yseam which is formed between the hook strip and the roof sheet andis also formed with a depending flange 1() nailed to the outer side 'of the fascia 4,

this arrangement being such that it does not interfere with any necessary movements of the roof sheet but closes againstthe entrance of water. any joints between the hook strip and roofframe which might otherwise a1- low a leakage.

lThe roof sheets are formed at their edges with upwardly4 and downwardly extending seam llanges 11, which have a hooked forma- .tion and are best 'seen in Fig. 3, these ianges being intended for interengagement with the upwardly inclined edges of the interior flanges 12 of the seam caps, this arrangement being show-n at the middle lportion of Fig. 3. The roof sheets and seam caps thus 'have a loose hooked interengagement which holds the caps from u ward displacement. The parts are assemble by sliding the seam caps, or the roof sheets, endwise.

At the outer end of each seam cap is formed a set of closing plates 13, 14 and 15,

these plates being preferably integral withl the seam eap. As or after the seam cap is `bent into its tubular formfjllustrated in Y ig. 3, the flanges 14 and 15 are bent at right angles to the longitudinal lineof the l cap so'as tomeet each other, as seen in Fig.

may be formed with invertedv U-shaped` l roof sheets from outward sliding, a oonnec- 5, and the closing plate 13 is bent downwardly to a position parallel with the plates 14 and 15 and overlapping the same, as illustrated in Figs. 4 and 5.

The arrangement is such that all openings into the outer end of the seam cap are closed, as seen in Fig. 4, and at the same time is formed an abutment against which the eaves ends of the roof sheet flanges 11 may engage so that the roof sheets will be held from outward movement toward the eaves.

vAt the ridge end the seam cap is provided or formedvwith an extension 16 in which is a perforation 17 for-*a bolt 18 (Fig. 2) which bolt connects together two seam caps at opposite sides of the roof which are in line with each other, and holds the saidoaps, as

well as the engagedl roof sheets from movement toward the eaves of the oar, at both sides of the latter. 'The bolt 18 preferably passes through the saddle 19top sheathing 3 and ridge pole 20.` The bolt will also pass through the ridge cap 21. s l

The ridge ends of the roof sheets are or flanges of usual construction, said flange of the sheet at oneside of the ridge interengaging with the similar flange of the'sheet at the other side4 of the ridge, the seam thusAv formed being inelosed by the seam cap 21, and at the ends of the ear byl ridge caps of suitable character.'l

What is claimed is 1. 'In a oar roof, the eombinationof a roof frame, roof sheets having upstanding hooked side flanges, seam caps having inturned hooked flanges loosely interengaged -with said flanges `of the roof sheets, means carried entirely by the seam caps for closing the eaves ends thereof and for holding the tionI holding together the ridge ends of the seam caps, and interengaging hook elements on the roof frame and on the eaves ends of the roof sheets whereby the roof sheets and seam caps are held from upward movement irrespective of anyseam slip.

3. In a oar roof, the combination of a roof frame, roof sheets having upstanding hooked side flanges, seam caps having inturned. hooked flanges loosely interengaged with said flanges of the roof sheets, means carried entirely by the seam caps for closing the eaves ends thereof and for holding the roof sheets from outward sliding, a Connection at the inner ends of the seam caps uniting them with the frame of the roof and` holding them from sliding outward, and interengaging hookv elements on the roof frame and on the eaves'ends of the roof sheets whereby the roof sheets and seam eaps'are held from upward movement.

4. In a carroof, the Combination of a roof frame, top sheathing carried thereby, roof sheets having upstanding side flanges, seam caps loosely inolosing the side flanges of the roof sheets and having laterally extending plates which Close the eaves ends of .the seam caps and act as stops against" the outward sliding of the roof sheets, a connection holding together the ridge ends of the seam caps, and nterengaging hook elements on the roof frame and on the eaves ends of the .roof sheets whereby the roof sheets and seam caps are held from upward movement.

5,. In a car roof, the combination of a roof frame, top sheathing carried thereby, roof sheets having upstanding downwardly hooked side flanges, seam caps loosely inolosing the side flanges of the roof sheets and having hook elementsV engaging with the hook elements of the roof sheets, and having laterally extending plates which close the eaves ends'of the seam caps and act as stops against the outward sliding of the roof sheets, a connection holding together the ridge ends of the seam caps, and interengaging hook elements `on, the roof frame and on the eaves ends of the roof sheets whereby the roof sheets and seam caps are held from upward movement. .l

6. In a car roof, the combination of a roof frame, top sheathing carried thereby, roof sheets having u standing side flanges,

seam caps loosely ine osing the side flanges of the roof sheets and having. inwardly extending transverse plates which close the eaves ends of the seam caps and act as stops v agamst the outward lsliding of the roof sheets, a connection holding together the ridge ends of the seam cap, and interengaging hook elements on the roof frame and on the eaves ends of the ,roof sheets whereby the roof sheets and seam .caps are held from upward movement.

7. A ear roof having in combination roof sheets and seam caps loosely engaged therewith, means for holding the seam caps from upward movement away from the roof sheets, means for holding the roof sheets from' outward sliding relative to the seam caps, means for loosely confining the eaves ends of the roof 'sheets against upward movement, and means for positively looking the seam caps from movement away from the ridge' of the roof.

8. A car roof having in combination roof sheets and seam caps loosely engaged therewith, means for holding the seam caps from upward movement away from the roo-f sheets, means for holding the roof sheets from outward sliding relative to the seam caps, means for loosely confining the eaves 'movement away from the ridge of the' roof. f

9. A seam cap for car roofs, embodying, an elongated sheet-metal member of tubular form provided with means along its sides for loosely engaging side anges of roof sheets disposed on opposite sides )of said member, and having its metal bent vto form a closed eaves end, substantially as speciends of the roof sheets against upward` l0. A seam cap for car roofs, embodying, an elongated'sheet-metal member provided with means along its sides for loosely .engaging side flanges ofroof sheets disposed on opposite sides of said member, and hav.-

ing, at its end, closure flaps bent inwardly toward each other to cover the end of the ward each other from the opposite sides of.
